JOHN A. WHERRY, OF NEW ORLEANS, LOUISIANA, ASSIGN OR TO UNDERWOOD TYPE-WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

TYPEWRITING MACHINE.

Application filed March 31, 1922.

To all whom it may concern:

Be it known that I, JOHN A. VVrInnnY. a citizen of the United States,residing in New Orleans, in the parish of Orleans, and State ofLouisiana, have invented certain new and useful Improvements inTypewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and particularly tomeans for en abling a condensed record-sheet or proofsheet to beinserted in the machine and detained therein in adjusted position whileother work-sheets, such as bills, statements,

or ledger-sheets, may be inserted, positioned, typed upon and removedfrom the machine in succession one after the other, so that the itemstyped upon each of the several latter sheets will all appear seriatimupon 2 the condensed record-sheet.

The object of the invention is to produce a device, of the kind abovenoted, of simple and inexpensive construction, and which may be embodiedin a usual or standard form of typewriting machine without the necessityof making any changes therein other than to install thereon theadditional-parts required by the present improvement.

The invention comprises a bail pivoted upon the platenframe and carryingadjacent its ends paper-guiding and holding devices, such aspape'nfingers, to co-operate with the front and upper part ofthe platenfor guiding an inner work-sheet, such as a condensed record-sheet,upwardly and.

rearwardly below and behind the front bar or front rod of the bail, uponwhich is mounted a gage for an outer work-sheet, such as a bill, astatement, or a ledger-sheet. 40 The usual releasable feed-rolls runningupon the bottom of the platen are cast off, and the bail, together withthe parts carried thereby, is swingable away from the platen to enablethe inner sheet or condensed record sheet to be adjusted prior to theinsertion of the first outer sheet. Said gage, which may be a side-edgegage, is pivoted on said front rod of the bail to swing away from theplaten, so as not to obstruct the insertion of the inner sheet orcondensed record-sheet, and to swing into proximity to the platen, sothat the outer sheet, when inserted, may be directed upwardly at thefront of said gage and the front rod of the bail, said outer sheet beingthus inserted and adjusted while Serial No. 548,294.

part of the rear paper-table for feeding the j condensed record-sheetdownward to the said usual lower feed-rolls and to the usual paperapronbeneath the platen, said rear feed-rolls being also effective toco-operate with said paper-holding devices or paper-fingers at thedelivery side of the platen to detain the condensed record-sheet inadjusted position in the machine during the insertion and positioning ofthe successive outer work-sheets.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a front elevation of the platenframe and parts carriedthereby of an Underwood Standard typewriting machine, having the presentinvention embodied therein and showing the parts thereof in theireffective positions. I

Figure 2 is a substantially central frontto-rear vertical section ofwhat is shown in Figure 1, and further shows, in broken lines, theside-edge gage for the outer work-sheet as tilted rearwardly on thebail-rod to a position providing for the insertion of the inner orcondensed record-sheet.

Figure 8 is a similar View, with the bail and parts carried therebyswung upward and rearward away from the platen to provide for adjustingthe condensed recordsheet.

In carrying out the present invention, a wide inner sheet 1, which is a.condensed record-sheet or proof-sheet, is inserted at the introductoryside of the revoluble platen 2 over an upper rear paper-table 3 havingan upper straight part and a lower part curved around the upper part ofthe platen at the rear thereof. Theupper rear papertable 3 is rigidlysupported upon the usual platen-frame by the end walls 4, in which theplaten-axle 5 is journaled, by means of lugs or sleeves 6 on the rearpaper-table 3, which are rigidly fixed, by means of set position, shownin Figures 1 and 2,

screws 7, upon the usual rear transverse tierod 8 which extends betweenandjtis-rigidly fixed in the upper part of the end walls 4 rearwardlyfrom the top of the platen and above the rear part of the platen. Theplaten 2 is now rotated, either by the usual line-space mechanismincluding the linespace ratchet wheel 9, or preferably and more rapidlyby means of the usual handle-knob 10, to feed the condensed record-sheet1 downwardly at the introductory side of the platen, such feeding ofthis record-sheet 1 being accomplished by means of upper rear auxiliaryor supplemental spring-pressed feed-rolls 11, which are mounted upon thepaper-table 3 by means of spring arms 12 which pressthese rolls towardsthe platen through openings 13 provided in the lower curved part of thepaper-tableB,

As the platen is rotated, the condensed record-sheet 1 is fed downwarduntil its leading edge passes upon the usual curved paper-apron 14beneath the platen. and ,be-

tween the platen and the usual normally effective releasable front andrear feed-rolls 15 which run upon the lower side of the platen. Bycontinuing the rotation of the platen, record-sheet 1 will pass upwardat the front or delivery side of the platen beneath curved paper-fingers16, adjacent the ends of the platen, and beneath spring-pressedpaperholding rollers 17 adjacent the upper parts of the paper-fingers,said paper-fingers 16 and rollers 17 forming paper-guiding andpaper-holding devices for "the condensed record-sheet 1. The advancingcondensed record-sheet 1 1s guided by the paper-fin ileath and to therear of a rod or bar 18 extending along the top of the platen and whichforms the front bar of a swingable bail having end arms 19 pivoted uponthe rear tie-rod 8 just within the frame ends 4 of the platen-frame. Theend arms 19, in which the frontbail-rod 18 is rigidly supported, havefront end parts 20 turned.

over inwardly at the front of the bail-rod 18, the upper ends of thepaper-fingers 16, as well as spring mountings for the rollers 17, beingsecured to these turned-over ends 20 by means of screws 21.

In order to position or adjust the con densed record-sheet to thedesired writing position, the lower feed-rolls 15 are now released bymeans of a suitable cast-off de-. vice, not shown, and the bail,comprising the side arms 19 and front bar 18, is swung upwardly andrearwardly from the effective to the ineffective position shown inFigure 3, thereby leaving the condensed record-sheet 1 free to be easilystraightened and adjusted, the light pressure thereon'of the rear upperfeed-rolls 11 not interfering with such adthe leading edge of thecondensed 'ers 16 around the platen. rearwardly bejustment. The swingingbail may be held at its forward position, in which the paperfingers 16and rollers l7 are effective, by means of a curved leaf spring 22carried within a U-shaped rear endpart 23 of one of the bail arms 19,for pressing a short rod or roller 24 into a groove formed along the"lower side of the tie-rod 8, as shown at the left in Figure 1. A similarholding device, not shown, is also preferably provided at the other sideof the machine. Thesedevices will also be effective to hold the bail atthe ineffective position shown in Figure 3.

After the condensed record-sheet 1 has been adjusted, the bail is swungforward from the Figure 3 to theFigures 1' and2 position, therebyrendering the paper-fin gers 16 and rollers 17 effective to co-operatewith the rear upper feed-rolls 11 for detainingthe sheet1' in themachine and holding. it in its adjusted position. While the condensedrecord-sheet 1 is thus detained and held and with the lower feed-rolls15 released, an outer narrower work-sheet. 25, which may be a billv or astatement or a ledger-sheet, is inserted at the introductory slde of theplaten over a lower usual rear paper-table 26, which may form part ofthe platen-frame, and.

which, in the machine illustrated in the drawings, is shown ascontinuous or formed in oneplece wlth the paper-apron 14L The outernarrower work-sheet 25 is pushed.

around from the rear over the paper-apron 1 L beneath or at the outsideof the C011. densed record-sheet 1 and above the released lowerfeed-rolls15 until its leading edge rises above the printing point onthe platen,

indicated in Figure 2 bythetype-head 27 carried by the, swingingtype-bar 28, and 1s .a'd usted'or straightened bymeans of the usualwing-scales, not shown. As theouter sheet 25 is further advanced, itsleading edge will pass to the front of thefloor portion 29 of agage-member or side-edge gage having an outstanding side flange 30against which the outer work-sheet 25 may be gaged laterally at itsadjacent side edge. This side-edge gage is carried by the front bar 18of the swinging bail, and in the normal or effective position of thegage the lowe-r edge of its floor portion 29 rests in proximity to thefront of the platen just above the printing line, as shown in Figures 1and 2, so as to be effective toreceive and guide the advancing outerwork-sheet 25.

To provide for the insertion of the inner condensed record-sheet 1, ashereinbefore described, the side-edge gage may be swung from itsnormally effective position, shown in Figure 1 and also shown in fulllines in Figure 2, to an upper position thereof,

shown in broken lines in Figure 2, so as not to obstruct the leadingedge of the advancing condensed record-sheet 1. Also during theadjustment of the condensed record-sheet 1, hereinbefore described, theside-edge gage for the outer sheet 25 swings with the bail-rod l8upwardly and rear wardly to the position shown in Figure 3, so as to beentirely out of the way. In order to provide fonswinging the side-edgegage between the two positions thereof, shown in Figure 2, it is pivotedon the bailrod 18 by means of a U-shaped portion, coinpiising ears 31and an upper connecting member 32, which is joined by means of anintermediate connecting portion 33 to the upper end of the floor portion29 of the gage. The entire gage-member may be formed from a single pieceof sheet-metal, as shown in Figures 2 and 3. The gagemember or side-edgegage may be slid along the bail-rod 18 between the paper-fingers 16 foradjusting it to different gaging positions. For frictionally holding thegage at its different positions of adjustment and also for holding it atits effective position, shown in Figures 1 and 2, as well as forfriction-ally detaining it at the ineffective position shown in brokenlines in Figure 2, a bowed leaf spring 34, interposed between theear-connecting member 32 and the bailrod 18, presses a small detentroller or rod 35 against the bar 18, and in the effective or gagingposition of the gage presses this roller or rod 35 into agrooveextending along the top of the bail-rod 18 throughout its length,as shown in Figure 2, for thereby more securely holding the gage at thegaging position. Of course, a carbon-papersheet will be interposedbetween the worksheets 1 and 25 and may be conveniently inserted alongwith the condensed record-sheet 1, and the forward end of thecarbon-sheet may be folded over the leading edge of the condensedrecord-sheet 1 in order to facilitate the insertion of these sheets.

During the insertion and adjustment of the outer work-sheet 25, as abovenoted, the inner condensed record-sheet 1 and its accompanyingcarbon-sheet are securely held in position in the machine by means ofthe upper rear feed-rolls 11 and the front paperholding devicescomprising the paper-fingers 16 and rollers 17. When the outer worksheet25 has been adjusted, as above noted, the lower feed-rolls 15 are thrownon or made effective and the typing may proceed, all the sheets beingadvanced or line-spaced by means of the usual line-space mechanism.Should the outer work-sheet 25 show any tendency to curl or fall overforwardly away from the floor 29 of the side-edge gage, such tendencymay be prevented by bringing into use the usual paper-guiding fingerprovided upon the Underwood machine to engage the paper adjacent to theprinting point, or, 1f desired, the gage may be swung upward on thebail-rod 18 to the broken-line position thereof, shown in Figure 2, andthe upper end of the outer sheet 25 may then be passed upward to therear of the bail-rod 18, but preferably is kept at the front.

Obviously, in the carrying out of the invention, as illustrated in thedrawings, the outer work-sheet 25 will be an original or ribbon copywhile the condensed recordsheet 1 will be a carbon copy forming a recordof all the items typed upon the successively inserted outer sheets.After the item or items which are to appear up on the outer work-sheet25' have been typed thereon, the lower feed-rolls 15 are cast off orreleased and the typed outer sheet 25 is then withdrawn from the frontof the machine, while the inner condensed record-sheet 1, containing acarbon record of what has been typed upon the outer sheet 25, isdetained in the machine and held therein in adjusted position by meansof the upper auxiliary or supplemental feed-rolls 11 and by thepaperholding devices at'the delivery side ofthe platen comprising thepaper-fingers 1G and pressure rollers 17. \Vhile the inner condensedrecord-sheet is thus securely detained in position in the machine,another outer sheet is inserted and positioned in the manner abovedescribed for the first outer sheet 25, and this last-inserted sheet isthen typed upon and removed similarly to the first outer sheet 25, andso on successively for any number of outer sheets of which it is desiredto make a carbon record upon the condensedrecord-sheet 1. It isunderstood, of course, that after any outer sheet has been gaged and thelower feed-rolls 15 made effective, all of the sheets may be line-fedforward to any extent desired or required by operating the usualline-space mechanism. Also, in case additional space is desired betweenthe successive entries on the condensed recordsheet 1, this sheet may,in the usual way, be independently line-spaced to the desired extentbetween the times of the insertion of the successive outer sheets.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
